>I'm not sure how much trouble you are having with Agrobacterium in
liquid culture but one antibiotic which can be a problem is gentamycin,
especially in minimal medium.We mainly use strains with the C58
background and these grow pretty much OK o/n in LB/LC without glucose.A
nice review of Agrobacterium electroporation just came out:
